Description
Technical field
The utility model belongs to building fastener areas, specifically, more particularly to a kind of swell fixture for building.
Background technique
Traditional expanding screw nail piece, some are used for connecting building wall and the fastener for connecting glass curtain.This is used for
The swell fixture of building includes screw, sleeve and nut, is rotated by nut and drives screw mobile, screw is while mobile
Sleeve expansion is driven, so that sleeve is made to withstand porthole to achieve a fixed connection, but the structural integrity connected is not high, there are one
Fixed security risk.
Utility model content
(1) technical problems to be solved
The technical problems to be solved in the utility model is the fastness improved between expanding screw nail piece and construction wall.
(2) technical solution
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: expanding screw for building
Screw assembly, for being plugged in the porthole of construction wall；It is described for building swell fixture component include nut and
Screw, sleeve, the first circular cone ring and the second circular cone ring in porthole are set；The axial ends of the sleeve is provided with several
The uniformly distributed notch of a annular, forms expansion piece between two neighboring notch, the screw sequentially pass through the first circular cone ring, sleeve,
Connect after second circular cone ring and nut and with nut thread, the expansion piece of the sleeve axial sides respectively with the first circular cone ring
The contact of incline plane on inclined-plane and the second circular cone ring.
In the above-mentioned swell fixture component for building, the step head of the screw is contacted with the first circular cone ring, described
Nut is contacted with the second circular cone ring.
In the above-mentioned swell fixture component for building, one end of the screw axial is provided with the connection of hexagon
Head.
In the above-mentioned swell fixture component for building, both the step head of the screw and first circular cone ring are connected simultaneously
It is an integral structure, the nut is contacted with the second circular cone ring to be connected and be an integral structure.
In the above-mentioned swell fixture component for building, the swell fixture component for building, which is characterized in that sleeve
Material be galvanized sheet.
(3) beneficial effect
The swell fixture for building of the utility model, by the way that expandable expansion piece and two is arranged at the both ends of sleeve
A circular cone ring while so as to pass through nut tightening, drives expansion piece to contact along circular cone annular strain and with the hole wall of porthole,
Therefore dual connection may be implemented, therefore it is stronger to connect swell fixture with porthole.
Detailed description of the invention
Fig. 1 is that the swell fixture for building of the utility model is mounted on the structural schematic diagram on construction wall；
Fig. 2 is the undeformed figure of Fig. 1 middle sleeve；
1 it is porthole in figure, 2 be nut, 3 be screw, 4 be sleeve, 5 be the first circular cone ring, 6 be the second circular cone ring, 7 is
Notch, 8 be expansion piece, 9 be step head, 10 be connector.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
A kind of swell fixture component for building as depicted in figs. 1 and 2, for being plugged on the porthole 1 of construction wall
It is interior；It include nut 2 and the screw being arranged in porthole 13, sleeve 4, the first circular cone ring 5 and the second circular cone ring 6；It is described
The axial ends of sleeve 4 is provided with the uniformly distributed notch 7 of several annulars, forms expansion piece 8, institute between two neighboring notch 7
Screw 3 is stated to sequentially pass through after the first circular cone ring 5, sleeve 4, the second circular cone ring 6 and nut 2 and be threadedly coupled with nut 2, it is described
The expansion piece 8 of 4 axial sides of the sleeve contact of incline plane with the inclined-plane of the first circular cone ring 5 and the second circular cone ring 6 respectively.
The step head 9 of the screw 3 is contacted with the first circular cone ring 5, and the nut 2 is contacted with the second circular cone ring 6, thus
The first circular cone ring 5 and the second circular cone ring 6 can be driven mobile towards 4 direction of sleeve, the step head 9 and the first circular cone of the screw 3
Both rings 5 are connected and are an integral structure, and the nut 1 is contacted with the second circular cone ring 6 to be connected and be an integral structure, therefore is tied
Structure is simpler.
The axial one end of the screw 3 is provided with the connector 10 of hexagon, can be fixed by connector 10,
To prevent screw 3 from rotating.
The material of sleeve 4 is galvanized sheet.
When installation, screw 3, sleeve 4, the first circular cone ring 5 and the second circular cone ring 6 are mounted in porthole, then nut set
It connects and starts to screw to make step head 9 that the first circular cone ring 5 and screw 3 is driven to drive the second circular cone ring 6 towards sleeve on screw 3
4 directions are mobile, and the expansion piece 8 by the inclined-plane of the first circular cone ring 5 and the second circular cone ring 6 with 4 two sides of moving sleeve is deformed towards porthole
1 direction is mobile and contacts with porthole 1, to make the formation of swell fixture component and the dual connection of wall, therefore connects more firm
Gu.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
